Archidekt! EDHREC has a community salt score they do a survey on every year so people do a "how salty does this card make you on a scale of 1-5" survey through what amounts to scryfall random once a year.
I believe EDHREC does a cyclic "salt score" voting round every... year? Where you can vote if a batch of randomly picked cards are considered salty or not, and it derives a value from that
